MMP20 SONO Mobil HD2 (option E)
CAUTION:
If you select "SAVE" at the end of the calibration, you overwrite one of the pre-configured
calibrations (or one you may have already modified) in the probe! The original
calibrations can only be restored with a PC and the Pico-Config software, as well as an
RS485 adapter (e.g. SM-USB).
Tip:
Back-up the calibrations you have saved on the probe to your PC using the "Pico-Config"
software and an RS485 adapter (e.g. SM-USB). This allows you to transfer calibrations
that you created to other probes.

Find probe
This menu item can be selected if there were problems communicating with the probe when the HD2
handheld device was switched on, or if a probe had not yet been connected when the device was
switched on, or if the probe is to be changed during operation. Once this item has been selected, the
HD2 makes another attempt to establish a connection to the connected probe. The serial number of
the probe appears on the display as soon as the connection has been established successfully.
"Probe not found" appears on the display if a connection cannot be established.
NOTE:
If it is not possible to connect to the probe even after several attempts, check whether
the probe is connected correctly. If this does not rectify the problem, please contact our
Service Department.

To start measuring the material, press the "Measure" key
again. Four measurements are taken to increase the accu-
racy. An average of these measurement values is then cal-
culated. The measuring time is approximately 20 seconds.
When the measurement is finished, the measured pulse
transit time is displayed briefly.
NOTE:
Before you start measuring, make sure that the
rods of the probe are fully immersed in the mate-
rial to be measured. The probe must remain in the
material for the entire duration of the measure-
ment and should not be moved.
After this, the calibration can be saved to the calibration
memory set at the start ("Save"). The selected memory is
only overwritten once the "Measure" key
word "OWN:" now appears in front of the original memory
name to clearly indicate which memory has been overwrit-
ten.
